Evaluation of Durability and Bond Strength of Polymer Powder-Modified Mortars With Accelerators

급결제를 이용한 분말수지 혼입 폴리머 시멘트 모르타르의 부착강도 및 내구성 평가

The purpose of this study is to evaluate the durability and bond strength of polymer powder-modified mortars with special accelerator components. The mortars were prepared with various polymer-binder ratios and applied to the concrete substrate as a repair material. Bond strength, flexural and compressive strengths, freeze-thaw resistance and carbonation resistance were measured for the test. As a result, bond strength of the mortars was increased with an increase in the polymer-cement ratio, and freeze-thaw resistance and carbonation resistance were significantly improved with increasing polymer-cement ratio also.
